Angle ABC and angle CBD or a complementary what is the value of X
Answer:
26degrees
Step-by-step explanation:
Find the diagram attached
From the diagram, Angle ABC and angle CBD are complementary hence;
<ABC + <CBD = 90
Given
<ABC = 2x
<CBD = 38
Substitute
2x + 38 = 90
2x = 90 - 38
2x = 52
x = 52/2
x = 26degrees
Hence the value of x is 26degrees

4x=y is your answer because if x is 5, like in the table, then 4(5) would equal 20, which is the y-value. It also works for every number in the table.
Hope this helps.
Stella rolls a standard six-sided die, numbered from 1 to 6. Which word or phrase describes the probability that she will roll a number less than or equal to 5? \text{impossible}impossible \text{certain}certain \text{unlikely}unlikely \text{likely}likely
The probability of getting a number less than or equal to 5 is 5/6.
What is probability?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".
For the given situation,
Stella rolls a standard six-sided die, numbered from 1 to 6.
The sample space for rolling a single die = {1, 2, 3, 4, 5, 6}
⇒[tex]n(s)=6[/tex]
The event is getting a number less than or equal to 5.
E = { [tex]{1, 2, 3, 4, 5}[/tex] }
⇒[tex]n(e)=5[/tex]
Thus the probability of getting a number less than or equal to 5,
[tex]P(e) =\frac{n(e)}{n(s)}[/tex]
⇒[tex]P(e)=\frac{5}{6}[/tex]
Hence we can conclude that the probability of getting a number less than or equal to 5 is 5/6.

Which equivalent expression can be used to solve the quotient 2/3 divided by 4/5
Answer:
5/6
Step-by-step explanation:
Divide it
The equivalent expression can be used to solve the quotient 2/3 divided by 4/5 is 5/6.
What is division?Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.
The equivalent expression that can be used to solve the quotient 2/3 divided by 4/5 is;
[tex]= \dfrac{\dfrac{2}{3}}{\dfrac{4}{5}}\\\\=\dfrac{2}{3} \times \dfrac{5}{4}\\\\=\dfrac{1}{3} \times \dfrac{5}{2}\\\\=\dfrac{5}{6}[/tex]

Janelle sells necklaces and bracelets online. She sells each necklace for $16 and each bracelet for $12. What expression represents the total amount of money Janelle made last month from selling a necklaces and bracelets
Pls help
Answer:
Y = 16a + 12b
Step-by-step explanation:
Given:
Cost of each neckless = $16
Cost of each bracelet = $12
Find:
Equation for the following state
Computation:
Assume;
Number of neckless sale in a month = a
Number of bracelet sale in a month = b
Total amount she earn = Y
So,
Total amount she earn = (Cost of each neckless)(Number of neckless sale in a month) + (Cost of each bracelet)(Number of bracelet sale in a month)
Y = (16)(a) + (12)(b)
Y = 16a + 12b

Draw a right triangle ABC. AB will represent the ladder, with point A being on the ground and point B being against the building.
Label: AC=6 ft, m<A=73° and <C is a right angle.
Use the trig mnemonic "SOHCAHTOA" to identify that BC/AC=tan<A. So BC, which is the height the ladder reaches, equals AC*tan<A=6*tan(73)=19.6 feet.
